TYPE SETTING AND DISTRIBUTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 467,640, dated January26, 1892.

Application filed August 24, 1891. Serial No. 403,537. (No model.)

revolving type-carrying table, by which the type are advanced to thedelivery devices for the line-forming or other mechanism.

lVhile the improvements forming the inven tion are of generalapplication in type setting and distributing machines employing such arevolving type-carrying table, they have been designed for use in atype-setting machine of the class shown and described in United StatesLetters Patent No. 232,157, 283,934, 372,186, 372,187, and 402,537, andwill be described in connection therewith, the invention consisting inpart of improvements on this machine.

In the machine shown in said Letters Patent the type are ejected fromthe channels of a cylindrical composing-case onto a rapidly-revolvingtable, from which as they arrive at the proper point they pass to thedelivery devices, which consist of guides for directing the type fromthe table and a type-conveying belt, by which the type are advanced tothe line-forming mechanism.

In the machine as heretofore constructed the type-carrying table issurrounded by a stationary guard, which consists of a rim of metalextending above the plane of. the table sufficiently to hold the typethereon and cut away opposite the delivery devices to allow the type topass from the table. It is desirable that the table should be run andthe type advanced from the channels of the composingcase to the deliverydevices at a very high rate of speed; but it is found that the highestspeed is not attainable with the construction described because thecentrifugal force resulting from the rapid rotary movement of the tablethrows the type outward against the stationary guard, and the drag ofthe type upon the guard checks their speed, so that the full speed ofthe table is not attained by the type. The drag increases with thecentrifugal force, and, consequently, with the speed of the table and ina higher ratio, so that it is impossible to secure a high rate of speedby increasing the speed of the table, the best results being attainedwith a comparatively low rate of speed. Moreover, the type are worn bytheir impact with the guard as they are thrown against it by thecentrifugal force and by the drag upon the guard as they are advanced incontact therewith by the table.

In the application of Elbert J. Andrews, filed April 24, 1891, SerialNo. 403,558, is shown and described means for avoiding these objections,which consists of a guard-belt moving with the table, this belt beingcarried outward from the table at the delivery devices and around anangular pulley above or below the latter, so as to permit the type topass from the table to the delivery devices.

I provide an improved construction in which the result desired isattained by a guard-belt which does not pass the delivery devices, butis returned about the type-carrying table from opposite sides of thedelivery devices, so as to avoid the latter, and is pref erably employedto drive the type-carrying table, although the latter may be driven byother means, if preferred.

In the accompanying drawings, in which I have illustrated my inventionin its preferred form in connection with a machine of the constructionof the patents referred to, Fig ure 1 is a plan view looking down uponthe type -carrying table and delivery devices, showing a portion of thecomposing-case in section, the construction shown being that in whichthe type-carrying table is driven by the guard-belt. Fig. 2 is a sideelevation of the same. Fig. 3 is a section 011 the line 3 3 of Fig. 1.Fig. 4 is a similar view to Fig. 1, showing a construction in which thetype-car- 5 rying table and guard-belt are driven inde- V pendently.Fig. 5 is'a side elevation of the construction shown in Fig. 4. Fig. 6isa section on the line 6 of Fig. 4. Fig. 7 is a section on the line 7of Fig. 4.

Referring to said drawings, it will be understood that A is thecomposing-case; B, the

revolving type-carrying table; 0, the guides between which the type passfrom the table; D, the type-conveying belt to which the type aredelivered and by which they are advanced to the line-forming mechanism,and E the driving-shaft for the type-carrying table, theconstruction'being substantially that of the patents above referred toexcept that the type-conveying belt D is carried below its normalposition to avoid the guard-belt and is guided upward by pulleys l toits position for receiving the type.

Referring now to the parts embodying my invention, F is a guard-beltextending about and in contact with the periphery of type-carrying tableB and extending above it sufficiently to hold the type thereon, thisbelt being guided by pulleys 3,-mounted on projections of the base-plateG, and returned outside them from a point slightly in advance of thedelivery devices.

In the construction shown in Figs. 1 to 3 the shaft E is not geared tothe type-carrying table 13, as in the construction of the patents abovereferred to, but is provided with a pulley H, by which the belt F isdriven, the belt in turn driving the table.

I preferably employ a roll 4, engaging the outside of the belt justafter it has passed over the pulley H and serving as a guide roll, thisroll being geared to shaft E by gears 5, thus being driven in the samedirection as pulley H and at a higher rate of speed, and beingroughened, as shown, so as to take up the slack and keep the belt tautabout the table; or the same result may be attained with greatercertainty by mounting the roll upon an eccentric-shaft, which ispreferably spring-pressed to allow the roll to yield to differences ofthickness in the belt. As shown in Fig. 1, the belt is so led as toleave but a short space between it and the guides 0, between which thetypes pass from the type-carrying table, and this space is filled by aguide 6, a similar guide 7 filling the space on the opposite side of theguides 0 between them and the first pulley 3.

In Figs. 4 to 7 I have shown a similar construction, except that shaft Eis geared to the type-carrying table by gears 8 9, as in theconstruction of the patents referred to, the guardbelt F being driven bypulley H, as before, but the roll 4 being in this case only a guide rolland not driven positively. It will be understood, also, that the tablemay drive the belt, although the latter will preferably be positivelydriven.

The operation of the construction will be understood without furtherdescription.

What I claim is 1. The combination, with a revolving typecarrying table,of a guard-belt moving in the same direction as the table and returnedabout the table to leave a space for the passage of type from the table,substantially as described.

2. The combination, with a revolving typecarrying table, of a guard-beltreturned about the table to leave a space for the passage of type fromthe table and by which the table is driven, substantially as described.

3. The combination, with a revolving typecarrying table, of guides bywhich the type are directed from said table, and a guard-belt moving inthe same direction as the table and returned about the table from pointson opposite sides of the guides, substantially as described.

4. The combination, with a com posing-case, of a revolving type-carryingtable receiving the type from the case, guides directing the type fromthe table, and a guard-belt moving in the same direction as the tableand returned about the table from points on opposite sides of saidguides, substantially as described. V

. 5. The combination, with revolving typecarrying table B, of guard-beltF, shaft E and pulley H, by which said belt is driven, and guide-pulleys3, about which the belt is returned, substantially as described.

6. The combination, with revolving typecarrying table B, of guides O, bywhich the type are directed from the table, guard-belt F, shaft E andpulley H on one side of said guides, by which the belt is driven, andguidepulleys 3, by which the belt is returned from the opposite side ofsaid guides, substantially as described.

7. The combination, with a revolving typecarrying table, of a guard-beltextending partially about said table, guide-pulleys about which saidbelt is returned, means for driving said belt, and a tightening-rollengaging said belt and driven in the same direction and at a higherspeed than the belt, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses. 7
